It is an old farmer's rule that garlic is toxic to dogs. But what's up? The fact that the plant - including onions, for example - can be harmful to the four-legged friends is mainly due to the alliin it contains, a sulfur-containing amino acid.
Garlic contains alliin
Alliin can have a negative impact on a dog's health - but the dose is crucial here. As a rule of thumb, to get an amount of the substance that is actually toxic, the dog would have to eat 5 grams of garlic per kilogram of body weight. For a four-legged friend who weighs 25 kilograms, that would be 125 grams of pure garlic a day. That makes around 50 toes of the spicy plant. This dose is of course very unlikely.

Toxic or not? It's the crowd that matters
So the answer to the question of whether garlic is toxic to dogs is yes, but only in excessive quantities. A small dose of garlic is even healthy for the dog. Veterinarians recommend around 4 grams of garlic a day as a health-promoting amount, which has a positive effect on the heart and circulation of the animal. Mix a little of the spice plant into the regular food of your four-legged friend - but of course only so much that the dog still likes it.
